Ornamenting rubber veneer and enamel



UNITED STATES PATENT FFICE THoMAS J. MAYALL, on READING, MASSACHUSETTS.

ORNAMENTING RUBBER VENEER AND ENAMEL.

SPECIFICATION forming part of Letters Patent No. 286,034, dated October 2, 1883.

Application filed June 22, 1881. No specimens.) I

To all whom it may concern.-

Be it known that I, THOMAS J. MAYALL, of Reading, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Improvement in the Art or Method of Ornamenting Rubber Veneers and Enamel, of which the following is a specification.

This invention is more particularly applicable to veneers made in accordance with the specification in my application for a patent for veneer filed May 7, 1881, and to enameled surfaces made in accordance with the specification in my application for a patent for improved method of enamelin g surfaces filed May 7, 1881; but it may also be applied to wood surfaces; and it relates to a method of embossing and printing simultaneously letters, figures, pictures,,and designs upon rubber veneering and rubber enameled and all other surfaces.

To practice my invention, I make an electrotype of the picture or design I Wish to emboss and print upon the veneer or enamel. The electrotype is inked just as it would be to print on paper, and is laid on the veneer, properly secured to keep it in its place and placed in a press having either the bed plate or press chambered for the admission of steam. Steam suflicient to heat the veneer or enamel moderately is admitted to the chamber in the press, and the press-is closed with force enough to embed the raised portion of the face of the electrotype .in the veneer or enamel. The impression and the color are both permanently fixed in the veneer or enamel.

It is obvious that any metallic blocks, with the picture, figure, or design required cut in relief on the face of them, may be used instead of electrotypes, and that any desired color 0 could be used. The color is applied with a roll,

as ink is applied in printing.

The electrotype or printing-block used may be made in reverse, so that the picture or design will be raised on the surface of the veneer or 5 enamel. The electrotypes or printing-blocks, made of metal that will bear to be heated enough to warm the rubber, veneer, or enamel, can be used in a press'without steam-heat.

The embossing and printing may be done 50 after thevulcanization of the veneer or enamel or the vulcanization may take place under the die. The best results, are, however, obtained by under-curing the rubber composition in the ordinary Way and then applying the emboss- 5 5 ing-die and raising the temperature to complete the vulcanization or curing. 1.

I claim as new and,my invention- 1. The above-described improved method or art of ornamenting rubber veneer and enamel, consisting of embossing and printing designs and pictures in the surface and on the surface, substantially as described.

2. As a new article of manufacture, rubber veneer embossed and printed substantially as described.

3. As a new article of manufacture, rubberenameled wood embossed and printed sub stantially as described.

THOS. J. MAYALL.
